A novel compound with the chemical formula of La2SrB10O19 has been successf
ully synthesized from the La2O3-SrO-B2O3 system via a solid stare reaction.
The power X-ray diffraction data is reported. It is Sound that the data sh
ow little difference from that of La2CaB10O19 which demonstrate that they a
re isostructural. The powder second harmonic generation effect of La2SrB10O
19 is about twice that of KH2PO4(KDP). The investigation of crystal growth
is in progress.
